honeycomb catalyst substrate
Detailed Product Description
Three -way catalysts will only give full conversion of each of these three pollutants in a gas stream containing a stoichiometric ratio of CO and NOx, as shown in the figure below.
There are many reaction pathways in a Three -way catalyst system, including those shown for the . The most important reactions for removing NOx can be summarised as:
2CO + 2NO -> 2CO2 + N2
[HC] + NO -> N2 + CO2 + H2O
